   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE

          MUCH OF WISCONSIN
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE ACROSS THE CENTRAL
   PLAINS.
   
   A STRONG JET STREAM DISTURBANCE NOW OVER MONTANA AND WYOMING WILL
   MOVE EAST-NORTHEAST ACROSS THE DAKOTAS LATER TODAY...AND ACROSS
   MINNESOTA AND SOUTHERN ONTARIO TONIGHT AND EARLY THURSDAY.
   
   AT THE SAME TIME...A SURFACE LOW ASSOCIATED WITH THE
   DISTURBANCE...NOW CENTERED OVER NORTHEAST SOUTH DAKOTA...WILL TRACK
   NORTHEAST INTO CENTRAL MINNESOTA THIS AFTERNOON...BEFORE CONTINUING
   NORTHEAST ACROSS LAKE SUPERIOR THIS EVENING.
   
   A BROAD CURRENT OF WARM AND VERY HUMID AIR WILL MOVE NORTH ACROSS
